fix: handle missing raw setup state (fix #2123)

[bgoscinski]

Description

When setup function returns render function there's no devtoolsRawSetupState and setupState is empty. When the same component exposes some data the loop will try to access it from the raw const. To prevent accessing property of undefined we'll default raw to an empty object.

I reproduced this here: https://stackblitz.com/edit/vitejs-vite-zhshuz?file=src%2Fmain.js

fixes #2123
